sciencehabit writes: ScienceNOW reports a rumor making the rounds on the physics blogosphere: the Cryogenic Dark Matter Search (CDMS), a small array of particle detectors lurking in the Soudan mine in Minnesota, has uncovered direct evidence of dark matter. This is the mysterious stuff whose gravity appears to hold galaxies together, making the discovery — if it is confirmed — potentially one of the most important of all time. But given the same team's previously published negative results and the relatively modest increase in the size of their data set, experts think a true signal is unlikely. We will find out in ten days, when the results are published in Nature.
